Electro Harmonix

Electro-Harmonix is a company founded by Mike Matthews which produces guitar effects pedals. The company has been going since 1968,
and is famous for its pedals such as the Big Muff Pi fuzz/sustain, the Small Stone phase shifter, and the Electric Mistress flanger.

The first Electro-Harmonix product was the Axis fuzz pedal, the entire production run of which was bought out by Guild and sold under
the name Foxey Lady. While working with Bob Myer on the early Big Muff design, Mike Matthews used a booster circuit Myer
had incorporated into the design and marketed it as the LPB-1 or Linear Power Booster in 1969. This massively boosted a guitar signal
to provide gain by clipping the signal, dramatically changing the sound. The new device provided a raw distorted sound, full of
sustain and harmonics. Several similar devices followed such as the Treble Booster and Bass Booster. The new devices were extremely
popular with guitarists.

Although the company stopped producing pedals beginning in the 1980's, Matthews was persuaded to start reissuing E-H's classic
pedals, as well as new designs, after he saw how much money was being paid for vintage guitar effects.

Still going strong, Electro-Harmonix produces a range of higher-end guitar effects pedals for a variety of sounds.
